Stop plot edges being cut off in bipartite package (plotweb)

Question

With the plotweb() function in the bipartite package in R, I've created a network, but some of the labels are too long for the plot area. As a result, they are being cut off at the top and bottom (I've included a picture).

I'm trying to make it fit in the plot, or if not possible, to be able to export it as an image without the edges being cut off.

I've tried par(mar=c(), but that doesn't seem to do anything. ybig() can allow the top half to fit in, but it doesn't change the bottom section.

Answer 1

It seems that the argument y.lim could be adjusted in such cases. From help(plotweb), about y.lim:

[...] Useful if labels are plotted outside the plotting region and for multitrophic plots [...]

Here is an example:

library(bipartite)

data(Safariland)
# Forge some long names/labels
cn <- colnames(Safariland)
rn <- rownames(Safariland)
colnames(Safariland) <- paste(cn, cn)
rownames(Safariland) <- paste(rn, rn)

# plotweb with trying to fit the labels - tweak y.lim until you get it right
plotweb(Safariland, text.rot = 90, y.lim = c(-1.5, 4))
